Abstract (en)

[origin: US2009120642A1] Provided embodiments relate to introducing a water-drainage-rate-enhancing agent into a subterranean formation to enhance gas production following a relative-permeability-modifier treatment to decrease undesired water production. An exemplary embodiment provides a method of treating a subterranean formation such that initiation of gas production is enhanced following the treatment, the method comprising: introducing a relative-permeability modifier into at least a portion of the subterranean formation such that the relative-permeability modifier reduces permeability of the portion to aqueous fluids; and introducing a water-drainage-rate-enhancing agent into at least a portion of the subterranean formation. Another exemplary embodiment provides a treatment fluid comprising a carrier fluid, a relative-permeability modifier, and a water-drainage-rate-enhancing agent.
